So theirs this question
Particle accelerators can be used to accelerate particles up to 95% the speed of light. Determine the energy released when 1 hydrogen atom collides with an anti-hydrogen atom.
E=mc^2
= (1.00794)(2.998x10^8 x 0.95)^2
= 1.00794 x 8.1225 x 10^ 16
= 8.1869 x 10^16...
So I am stuck on another question I've been looking at
Ina brake test on dry concrete a Porsche Boxter traveling with an initial speed of 33.2 m/s can stop w/o skidding after moving 62.8 m . The mass of the Boxter including driver is 1340kg.
Determine the magnitude of the average...
A cart on a surface with a coefficient of friction of 0.20 is attached to an overhanging weight. THe cart has a mass of 2.5 kg while the overhanging weight has a mass of 1.0 kg.
Determine the Acceleration
Hanger Fg = 9.8 N
Cart Fg = 24.5 N
Fk = 4.9 N
A = Fnet/m
= 4.9 N/2.5...
